Photorefractive Keratectomy (PRK) Laser Eye Surgery


This improves vision by reshaping the surface of your eye's cornea. That's the clear outer layer at the front of your eye. PRK can treat nearsightedness, farsightedness, and astigmatism.

Eye exam

Before surgery, your eye doctor carefully examines your eye. The shape of your cornea is measured and mapped. This data is put into a computer that controls the laser.


When it's time for your surgery, you're given medicine to help you relax. Drops numb your eye. Your eyelids are held open to keep you from blinking.


The doctor carefully removes a layer of cells from the surface of your cornea. Then, the laser reshapes your cornea. The new shape will help the cornea focus light properly.

After the procedure

After the procedure, you'll wear a special contact lens to help your eye heal. You'll use medicated eyedrops. And, you'll have followup appointments to check your vision. Follow your doctor's care plan.
